Abstract

Finite-volume discretizations of the hydrodynamics equations introduce discretization error into computed solutions. This error may be a significant component of the uncertainty in simulation results. Therefore, discretization error quantification via calculation verification is vitally important to computational fluid dynamics analysis. Previous work has demonstrated the capability to perform calculation verification with not only monotonic but oscillatory convergence in Cartesian coordinates. This work will demonstrate results of a software framework developed to perform code verification and calculation verification on Cartesian and non-Cartesian geometries. Results on multiple grids will study the validity of the assumed error ansatz and evaluate the quality of the estimated errors. Local convergence information, including convergence rates and error estimates, are given for each cell in the coarsest grid.
